Thanks @jaimeMF, it works here with your 1b26296

The tests also fails on Travis, does it works for you?

phihag · 2014-07-20T18:03:55Z

You're right, the issue persists. Can somebody with flash player provide a correct set of before-and-after signatures?

jaimeMF · 2014-07-20T18:37:39Z

Before -> After

phihag · 2014-07-20T18:46:36Z

That's strange, our code outputs these already (added test in b6ea11b ).

jaimeMF · 2014-07-20T19:15:18Z

It turns out that changing one of the parameters in the get_video_info url, gives the correct urls. So the swf interpreter is working fine (nice job!).

phihag · 2014-07-20T19:39:50Z

Excellent! Confirmed working with youtube-dl 2014.07.20.1 .

Nurple · 2014-07-20T21:03:50Z

The problem still exists for me on Windows.

@Nurple Your problem is completely unrelated, but I've tracked it down to an overly old Python version. Fixed in youtube-dl 2014.7.20.2.

Nurple · 2014-07-20T23:21:13Z

Sorry about that, I thought it was related. Anyway thanks for the quick fix.
